Zophar first appears in the personal property tax list under Daniel Brown's district in 1812 on March 28.
Zophar Johnson 1 male 1 horse

If I am reading this correctly, this tells me that Zophar had 1 son and 1 horse on March 28, 1812? At this time Zophar & Elizabeth would have had 1 son John born 6/1811 and a daughter on the way 7/15/1812/ I am also assuming females were not listed here?

I also assume Benjamin, William and Nathanial Johnson were all related in one way or another to Zopher?
